ABSTRACT

ABSTRACT: The effects of three different tactile types on the performance of identifying six tactile symbols are reported. Thirty participants were asked to identify eighteen randomly assigned tactile symbols which differed in their tactile modality (Solid-face, Slant-line, Swell-dot), and their tactile shape (Square, Circle, Triangle, Inverted-Triangle, Rhombus, Cross). The accuracy of identification and the mistaken pairs of tactile symbols were recorded. Repeated measure of ANOVA shows that the Solid-face has the higher identification accuracy than the Slant-line and Swell-dot type. Within those six tactile symbols, the Square, Triangle, and Inverted-triangle have a higher accuracy than the other three shapes. From the mistaken-pair table, Circle is easily mistaken for Rhombus; and Rhombus is significantly mistaken for Circle, and the Cross symbol is mistaken for the Circle or Rhombus. The implications of this result are discussed.
